SAW-SET.

SPECIFICATION forming part of Letters Patent No. 408,759, dated August 13, 1889.

Application filed March 1889. Serial No. 303,464. (No model.)

T at whom it may concern:

Be it known that I, SIMON SHOUP, a citizen of the United States, residing at Fish Lake, in the county of Elkhart and State of Indiana, have invented new and useful Improvements in Saw-Sets, of which the following is a specification.

The invention relates to improvements in saw-sets; and it consists in the construction and novel combination of parts hereinafter described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended. v

Figure 1 of the drawings represents a perspective view of a saw-set embodying the invention. Fig. 2 represents a central vertical longitudinal section thereof. Fig. 3 is a perspective view of the lower end of the upper die or plunger. Figs. 4 and 5 are perspective detail views of one of the gage-plates and of the anvil-plate.

Referring to the drawings by letter, A designates the circular base of the main frame; B, a horizontal arm standing radially outward therefrom; and O, the bed to rest the gageplates, which bed-rest crosses the base diametrically at right angles to the arm B, havinga dovetailed notch c aligned with said armat its center for the insertion of the lower die or anvil D, which has beveled edges to fit in said notch, and on. its upper side the'oppositely-inclined faces d cl, meeting at their highest points in a transverse ridge, as shown.

E is a standard rising from the rear of the gage-rest and having upon it the two frontwardly-standing bearings e e for the cylindrical plunger or upper die F, which die has the outstanding pin f at. a proper point and is surrounded between said pin and the lower bearing 6 by the coiled spring f, which bears against the pin f, forcing the same against the upper bearing and lifting the plunger. The lower end of the plunger is provided with the two faces G G, meeting in a transverse ridge and inclined oppositely at equal angles, each face being parallel to the face d on the anvil when thereabove. The face G is intended to be used for setting the teeth of crosscut-saws, while the face G, which is. made smaller than the face G by the bevels g on the side of the plunger, is used to set' the teeth of smaller saws. Either face can be turned to stand over the face (Z by means of the outstanding pin f, which can be turned to rest against the standard E on either side of the plunger, which can thus make one-half of a rotation in its bearings.

WVhen the anvil is properly seated in the notch c, the ridgebetween its faces 61 d is vertically below the front or adjoining side of the plunger.

ll-H are similar rectangular gage-plates, with their lower edges resting upon the bed C on each side of the notch c, and provided with the stems 71-, which enter openings in the standard below the lower bearing 6, so that the gage-plates can be set farther in or out thereby.

L L are set-screws entering threaded openings in the shoulders of the standard and impinging upon said stems to hold the gageplates in position when set.

J is a vertical adjusting-screw entering a threaded recess in the arm B, near the end thereof.

The operation of the device is as follows: The anvil is first set in position and the plunger turned to present the desired face thereto. The gage-plates are then set in or out, according to the size of the teeth of the saw to be operated upon. The blade of the saw is then rested upon the head of the screw J, with its teeth against the gage-plates. The saw is then moved along, every second tooth being set in the same direction by driving the plunger down upon it as it lies upon the anvil by means of a hammer. To set the'intermediate teeth, the blade is turned over and operated upon as before. By raising or lowering the screw J the inclination of the blade is varied to give the teeth more or less set, as desired.

The gage-plates are made long enough to prevent the teeth of a screw when wide apart from straddling them and thereby throwing the saw out of proper alignment.

Having described my invention, I claim- 1. In a saw-set provided with opposite bearings, the reciprocating punch F, having the face G and opposite inclined faces g g and intermediate inclined face G, and provided with the-pin f for rotating the punch, substantially as specified.

2. In a saw-set provided with opposite bearings, the reciprocating punch F, having the face G and opposite inclined faces g g and intermediate inclined face G, substantially as specified.

3. In asaw-set havinga standard provided with opposite perforations, the opposite T- shaped guides II, mounted on the base and having stems h inserted in the openings in IQ the standard, and set-screws L,, inserted through the standards and bearing upon the stems h, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

SIMON SI'IOUP.
